Rising costs, climate change prompt shift to solar

An energy expenditure that had been climbing by around 10 per cent per year coupled with concerns about climate change have prompted St George cotton irrigators Ian and Anne Brimblecombe, “Burgorah”, to install solar panels which generate 100kW of electricity.

Their 400 250-watt solar panels will soon be joined by a supplementary bank of panels which will enable a 70kW fixed-speed pump to be powered by solar alone on sunny days.

Emissions Reduction Fund: ‘fertiliser efficiency in irrigated cotton’ method

The Department of Environment has been busy over the last year making new greenhouse gas emissions reduction methods available for use under the Emissions Reduction Fund (ERF). A number of these are designed to benefit the farming sector, including a ‘fertiliser efficiency in irrigated cotton’ method released in December 2014.  

Water running short? How do we manage our irrigations?

When water is limited growers may need to change from their normal irrigation practice to optimise yield, quality and water use efficiency. As with fully irrigated production, the aim is to limit or minimise the amount of stress on the crop. Cotton’s response to water stress depends on the stage of growth that stress occurs, the degree of stress and the length of time the stress is present.

Late season irrigation management

Many crops, particularly in the northern regions, are fast approaching cutout. Cutout occurs when the plant has 4-5 nodes above white flower (NAWF) and generally occurs late January to mid February. This is the time of the last effective flower which can be used to plan irrigations after cutout.  End of season water requirements can be determined by estimating the number of days until defoliation and predicting the amount of water likely to be used over this period.

Crop walk and breakfast - Southern NSW (Darlington Point)

The Southern Valley's Cotton Grower Assoication is inviting southern NSW growers to a crop walk and breakfast on Thursday 22 January.

Taking place at Point Farms, the walk will cover five key topics:

  • Nutrition trial - the importance of N and P in the system (Incitec/Yenda Prods)
  • Pix rate observations - methods adopted for 2014-15 season
  • Practical use of crop imaging
  • Nitrogen uptake and efficiencies (Kieran O'Keeffe, regional development officer, CottonInfo)
  • Thrip trials (Sandra McDougall, entomologist, NSW DPI).

Date: Thursday 22 January

Time: 9:30am

Location: Point Farms (meet at Main Shed), Darlington Point
